Oops even worse, about 1/4 gal. Don't get me wrong, I was at the 240 or so range and I know my other ran great at 260-270 or so. I do not tune by temps but I like to see the numbers, beside, I do not even own a temp gun. I noticed the low end like it rich.. I did the pinch test and it ran too long. I started leaning the bottom, but had an adverse affect. So I went with it that way.
